The path of least emissions may not always be the fastest way to drive somewhere. But according to new research from the University at Buffalo, it’s possible for drivers to cut their tailpipe emissions without significantly slowing travel time.In detailed, computer simulations of traffic in Upstate New York’s Buffalo Niagara region, UB researchers Adel Sadek and Liya Guo found that green routing could reduce overall emissions of carbon monoxide by 27 percent for area drivers, while increasing the length of trips by an average of just 11 percent.More>>
